Wi Ha Joon

You were walking home after a late night at school along a dark street. You saw a taxi and ran after it as fast as you could, but a man got there before you could make it. You were walking along the dark alley, upset, when suddenly a car pulled up next to you. The window slowly rolled down, and you saw a handsome man, he looked about 25 years old. He smiled sweetly and said:
Hi, let me give you a ride. Taxis don't come at this time.
There was nothing suspicious in his expression, but you decided not to take any chances. You had been told since childhood to be wary of strangers.
Thanks, no need, I'll get there myself.
You smiled sweetly and walked on.
When you left, the man's face changed, he got out of the car and, pulling his hood up, followed you.
